Excellent - I Love This App – Heart Graph Review

My uses: HIIT - 5 sets of 30 sec with rest to heart rate of 110 bpm. As my fitness improves the time of the rest period decreases. Eventually I increase the amount of resistance. Jog - 20 min of moderate intensity, bpm 130 - 140. Eventually I need to increase the resistance. The advantage with Heart Graph is that I no longer rely on my faulty measurements of 'perceived intensity' for judging workouts. I compare the graphs over time to see the increase in my fitness.
